YDANIEL I.. HEALY,v or s-AN FRANCISCO, CALIFORNIA;

PLOW.

Application filed November 1,8, 1918. SperialNo. 262,926.

To all whom t may concern: Y

Beit known that l, DANIEL L. HEALY, a

citizen oi the United States, residing at San llrancisco, in the county ot' San Francisco, citate of California, have invented a new and usei'ul Plow, ot which the following is a specification, in such iull and clear terms as will enable those skilled in the art to construct and use the same.

his invention relates to a plow of the general type known as a gang plow and its particular plow is intended to be used in conjunction with a series ot similar plows all operatedtogether. Y' i @ther objects oi the invention will appear as the description proceeds. I

in embodiment of the invention is shown in the drawings in which thesame reference Y Vnumeral is applied to the saine portion throughout, but l am aware that there may be modifications thereof. l

Figure 1 is a plan view or" the complete plow with its steering frame,

Fig. 2 is a side elevation ot the complete plow and steering trame, Fig. 3 is a side elevation oit the furrow wheel and its segment guide,

et is a iront elevationo't the furrow wheel see'ment guide showing the brace for attaching it to the trame of the steering gea?,

i" j. 5 is a plan view or" one of the axles plow, j "e. 6 is a back elevation or the lever for i. K or lowering the line of pull upon the plow, ant

T is a side elevation V"of one ofthe bdraw bar has suitable iron sA ig and stifiening it. These s minate lugs?) and 4 for the at-v t l draw banbut which acnnient to anoth 'forms no tart of the present invention. T he draw bar 1 nas a stiiiening plate 5 across its top at the iront of which is an eye bolt 6 to which the plow drart link 7 is connected.

The draw bar has two n other reinforcing plates S and 9 which plates have caster wheel brackets 10 and 11 mounted on caster wheels 12 and 13 at the front of the machine.

it the rear of the plates 8 and 9 there are depending brackets 14 and 15 in which are journaled wheels 16 and 17, so that the draw I bar is supported by means of the wheels 12 13 andV 16, 1T. The draw bar is steered by Speccaton of Letters Patent; .Patll'td' NOV. A16,;1920.

means of the two poles 18 and 19 which arevv connected to the forward portions of the caster wheel frames 10 and 11. In order to hold the draw bar mechanism in the proper position with respectto the furrow wheel 2() which is mounted on an arm 21 pivotally connected to the depending lugs 22 carried by the draw-bar, there are two of the arms 21 united at their rear end ina slide 23. This slide is freely movable inthe segment guide 24. i This guide is carried by the bar 25sup'- ported at its front end by the draw bar l. rlhe guide is braced by means of a diagonally extending bar 26 which extends from` the lowerportions ot' the segment guide to the draw bar 1. ,e l v 'Y The plow. drag link 7 passes through an elongated link 28 which isnsupport'ed by a lever 29 pivotally mounted on the post 30 on the back of the draw` bar 1. A depending bracket 31 holds the link inthe proper alinement; and said bracket is'braced by means of a bar 32 which extends at an angle therewith, and is connected with the draw are joined together at their ronten'ds, l'and' which stand atv a distance from eachother at their rear ends; each being connected .to

a plow standardy as indicated at'35 and 36. These standards have mold boards 37' and 38 connected therewith respectively. e

The drag link .7 is connected with'the'ring 39 at the front end of the plow beams which' ring is adjustable ast-o heightin the two depending` brackets tl-and 41. bracketsl have braces {l2-'and 43 connecting them with the plow beams. rI herplow is supported when at work by the'mold boards and by'means of the two wheels 4-6 and 477:'

@ne oit these wheels is ca 1rie'd bya stub axle 43 detachably connected with a transversely extending axle r9 which axle {1t-9 has a block 50 at one end for the connection of the stub axle thereto. The stub axle is threadedto receive a screw 5,2 on a block 53 which block holds it rigidly when mounted as shown in Figs. 1 and 2. At the other end of the axle there is a rigid spindle 51 for the wheel 427, and this wheel may be held in place by the screw 52 and block 53 to which axle may be connected. n

The plow illustrated in this invention is intended to be used in connection with `a another plow ,series of other plows and when so used, has

flexible axles connected to the ends of the axles 49; but in the present instance, the

blocks 53 are used to hold'the wheels 46and 47 in the desired rigid position. v

The axle 49 has two drag links, 56, 57 con- Vnected thereto, which links are connected with the lower end of a lever 58 pivotally mounted thereon on the frame ofthe plow and adjusted by means of the segment rack Vthe upper end ofthe bar 61 thereis a flat plate 65 which has a series of holes therein in order to enable the lever 66 to be connected therewith in different adjustments as may benecessary.. The plows are lifted Y Y yout'of the ground by depressing the forward end ofthe lever 66, V'which is held in any given adjustment by means of the latch 67, engaging suitable'notches .in thef rack bar 68; while the rear end of said lever is con- 'nectedvbymeans of a ring 69 and two links 70, 71.with therear ends of the plow beams. Since this particular plow is intended to be used in conjunction with an entire set of seeding apparatus, it has a rearwardly extending pole72 to which the seeder is con- ,nected byv means of a movable clevis 7 3. The

firstV plow of the sethas arms 74, 75 connected thereto which are in turn connected toa beam 76 for the purpose of pulling the harrow 77. Said harrow is connected to the plow beam 76 by means of two links 7 8. 79. This bar 76 is held ina fixed position vwith respect tothe plows byy means of rods 80,

8l and turn-buckle 82, -which rods are coni nected toa ring 83'atv the'rear end of the .platefS on the main draw bar.V

j' In operation the apparatus is connected to any suitable source of power traction engine,'or a team, as may be desired. and is steered bylneans of the caster wheels'12 and 13, the furrow wheel 20 holding the plow steering mechanism in the desired track.

VV,theapparatus is drawn forward, the

plows will turn over the furrow, the depth of the furrow being regulated by means of the lever 66; and as such regulations take place, the rods 56, 57 are kept tight by means of the lever 58.

The draw bar is made sul'liciently wide to afford a walk for the rlowman.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is as follows, express reservation being made of permissible modifications: Y

l. In a plow, the combination of a wheeled draw bar, a vertically movable pivotedarm connected with the draw bar, a furrow wheel carried by the arm, a plow frame connected Vwith the draw bar carrying a plurality of mold boards and having a pair of supporting wheels vertically adjustable with re? lspect to the frame of the plow.

2. In a plow, the combination of adraw bar, wheels Afor supporting'said draw bar,

a furrow wheel movable vertically for assisting in steering the draw bar, a plow frame connected with the draw bar, a plurality of mold boardscarried by said plow frame, a pair of adjustable wheels for determining the depthV of the furrow to be produced and for supporting the plows, and a pair of links for holding the plow wheels in a lixed position longitudinally with respect to the plow frame'. o

In a plow the combination of ya draw bar, fixed wheels and caster wheels support- 1 ing saidrdraw bar, a vertically movable furrow wheel to assist in tracking the draw par, and a gang plow connected to the draw ar. Y 4. In a plow the combination of a draw bar, fixed wheels and caster wheels for supporting said draw bar, an'arm pivoted to the draw bar at one endV and freely movable vertically, a furrow wheel connected with said arm forrguiding the draw bar, and a gang vplow connected with the draw bar so placed asto'` cover the furrow in which the furrow wheel travels.

,In testimony whereof I have hereunto set my hand this 8 day of NovemberrA. D. 1918. Y Y Y DANIEL L. HEALY. A
